0 ohms is short, not blown bulb
OL or very high reading is open circuit, blown bulb, bad connection, etc.

12 V OFF, just test across the 2 wires
leading to the light…disconnect them at the base of the mast, a reading
of zero ohms suggests a blown bulb, bad connection for the bulb or broken wire
(s).

Advice?
Dennis:
Thank you for the step by step advice. I have the meter here now
and it reads "0 ohms" when I touch the red and black probes......my
meter reads "1 . " when not touching.....not OL (out of limits)
..... I guess all meters are not the same.
One more question.....when I do this test, do I have the 12V switch for the
mast head light ON or OFF at the electrical panel?
I told you I was no electrician!
